1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 1,2-ethanediol and 2,2'-[(octahydro-4,7-methano-5H-inden-5-ylidene)bis(4,1-phenyleneoxy)]bis[ethanol] CAS 109721-30-4

Description

Compared with other compounds in its class, the molecular weight of 664.79 g/mol gives 1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 1,2-ethanediol and 2,2'-[(octahydro-4,7-methano-5H-inden-5-ylidene)bis(4,1-phenyleneoxy)]bis[ethanol] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 1,2-ethanediol and 2,2'-[(octahydro-4,7-methano-5H-inden-5-ylidene)bis(4,1-phenyleneoxy)]bis[ethanol] (CAS 109721-30-4), a certified reference material (molecular formula C26H32O4C10H10O4C2H6O2, MW 664.79 g/mol) for analytical method development and quality control.

The molecular framework of 1,4-Benzenedicarboxylic acid, 1,4-dimethyl ester, polymer with 1,2-ethanediol and 2,2'-[(octahydro-4,7-methano-5H-inden-5-ylidene)bis(4,1-phenyleneoxy)]bis[ethanol] (C26H32O4C10H10O4C2H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
